一种智能的大规模MIMO部分导频复用调度方案
Smart Assignment Scheme of Fraction Pilot Reuse for Massive MIMO
摘要
Abstract
Pilot contamination is known to be one of the main bottleneck for massive MIMO multi-cell communications. Different from the existing pilot allocation schemes,a new pilot allocation scheme is proposed to restrain the pilot contamination. The key idea is to a fraction of users within each cell reuse the same pilot subset across the whole system,in which the base station firstly measures the inter-cell interference of each pilot sequence of the reuse subset. Then,the propose scheme assigns the pilot sequence with minimum inter-cell interference to the user having the worst channel quality in a sequential way to improve its performance. While the rest of users reuse the orthogonal subset among the non-adjacent cells. Analysis and numerical results show a remarkable improvement compared with the existed scheme and can restrain the pilot contamination effectively.关键词
